Genitourinary medicine (GUM) is an expanding specialty which is primarily related to the treatment and prevention of sexually transmitted infections (STIs). A large part of the work is involved in the clinical management of patients with HIV infection at all stages of disease, including inpatient management. The work involves a number of non-infectious medical genital problems such as dermatoses. A number of GUM departments also offer other sexual health services such as contraception, colposcopy (for the diagnosis and treatment of cervical dysplasia) and sexual dysfunction.
